Armenia and Sri Lanka perhaps had similar performances: not being particularly strong but surviving into the endgame anyway. In Armenia’s case they were not afraid of a good fight, whichever way it went. Predictable wars against Israel went well for them, but not many others- and eventually they were incapable of stopping the Spartans’ rampage. Confined to three cities for much of their final days, Armenia’s size was probably not an accurate reflection of their strength - it took both Sibir and the Boers to bring them down.
